Application filed December 10, 1908. Serial No. 466,877.

erably made in two or more longitudinal.

sections, into the bore or recess of the box. In the drawing F gure 1is-a plan view of one type of divided box showing the cap or top partremoved. :Fig. 2 is a cross section of the same showing the cap inplace.Figs.

3,4 and 5 show details and modifications.

A represents the main portion of a journal-box having a capB, fittedinto-it; this box is of the side flanged type, but my invention isequally applicable to an ordinary half box and cap as well asto-otherforms of journal boxes which are divided for the purpose oftaking up wear. i

C is a lining forming the bearing for the journal, and is madepreferably in two parts longitudinally, but if required can be made inas many parts as it is desirable to sep-v arate the box into. Thematerial for-the linings may be brass, Babbitt metal or any suitablemetal either cast to size or machined. I prefer that the parts of thislining project slightly beyond the division lines 5 of the box. asindicated. in Figs. 3 and 4, and clamping plates D are provided pressingagainst the edges of the lining sections, and secured to the adjacentparts of the box and cap (or boxsections) by means of screws 1. Itwill'be seen that the clamping plates may lie in a rabbet formed in theedges of lining sections, so that practically the entire inner surfaceof the lining can be utilized for hearing purposes. The screws 1, andclamps D, force the lining sections against the interior periphery ofthe box, so as to produce rigid contact and'con sequently a solidbacklng for the lining. This is an important result especially forjournals running at a high speed, where vibration must be eliminated.

In order to further insure such rigid contact of the box, I provide awedge-like or beveled lip 4, on oneedge of the clamping plates D, whichfits into a corresponding as circular in section an groove in the edgeof the lining sections G. hen therefore the plate D is forced down bythe screws 1, the action of the beveled lip dis to wedge or thrust thelining radially, or nearly so, into the bore or recess 0 the box, andthus produce rigid contact around the peripheral surfaces.

It will be observed that by means of the projection of the edges of thelining beyond the division lines of the box, I secure a clearancebetween the plates D, and the ledge 5,-01' parting line of the'box, asindicated in Figs. 3 and 4. This is for the purpose of insuring clampingpressure on the lining sections, and I have indicated in Fig. 2 that theplates D may be pitched slightly away from a radial line so as to have abearing on the parting ledge 5 of the box at-one edge, and on the liningsection at the opposite edge. Other means of utilizing this clearanceare shown in Fig. 3 Where a slight bearing lip 3 is provided, forming afulcrum upon which the clamping plate is supported along one edge whilethe other edge is forced against thelining section bythe screws.

In Fig. 4 a compressible or elastic strip is shown under the clampingplate, thus parclamping plates to perform their function,

but in practice this clearance is desirable for the purpose of providingagainst slight and insuring the acinaccuracles of fitting tual contactof thelining and the box by the clamping pressure.

I have shown the linin space in the box' the lining asannulan, becauseboring the box and turning the lining on casting it in an annular moldmade in sections to correspond withthe dimensions of'the box, isapparently the most practical method of producing the complete ox; butother forms of lining space, either machined or left rough from the moldor forge, or of polygonal or square cross-section, may be used inconnection with my invention, the lining sections in such cases beingcast into the box or otherwise roughly fitted.

. interior of the box notwithstanding variations in the lining sectionsor in the box.

2. In a journal box comprising separate parts each haying ledges orsupporting clamping plates, lining sections in the parts of the journalbox, clamping plates supported on said ledges and bearing on proximateedges 01": the lining sections, there being a lip at an edge ofeachclamping plate on the ledge side thereof whereby the body of eachplate stands away from its ledge and means for securing the clampingplates to the. ledges and firmly pressing the lining sections againstthe inner surface of the parts of the box notwithstanding variations inthe sizes of such parts.

3. A journal box comprising separable parts having plate-supportingledges, de tachable lining sections in the parts of the box, clampingplates on the ledges, the clamping plates each having a projecting lip,or lips, on the side facing its ledge, one edge of each plate normallybearing on an edge of a lining section, the bodies of said platesadjacent such edges being separated from the supporting edges toprovide. adjustment against Var tions in lining sections and boxes, andp ate-clamping screws.

4. In a journal box comprising separate parts, removable linin s made insections longitudinally, edges of said sections having bevel grooves,clamping plates having beveled lips fitting into the correspondinggrooves in the edges of the lining sections, means for securing saidclamping plates to the parts of the box, whereby the sections are forcedradially or approximately so, against the inner periphery of the box,for the purposes set forth.

5. In a journal box comprising separate parts, removable lining sectionswith their longitudinal edges projecting slightly beyond the divisionlines of the box, clamping plates for securing said linings in theirrespective recesses, means for securing said clamping plates to theparts of the box, there being a clearance under the clamping plates,whereby pressure is exerted mainl on the lining sections, for thepurposes set fortln 6. A journal box comprising a plurality of separateparts, a lining for each part of the box, adjustable clamping plateswith beveled parts bearing on the lining sections in approximately aradial direction, the edges of the lining in each part of the box havingsurfaces cooperating with said beveled parts of the clamping plates, andmeans for securing such plates to their respective parts of the box.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
